The fired Los Angeles police officer suspected in the murder of an Irvine, Calif., couple and the shooting of two Riverside, Calif., officers — one fatally — reportedly said on his Facebook page that his violent spree is payback against his former supervisors, and that he plans a deadly vendetta against those who he says mistreated him.

Law enforcement officials have launched a massive manhunt for Christopher Jordan Dorner, 33, who is a suspect in the shooting deaths of Monica Quan and her fiancée Keith Lawrence on Sunday. Quan’s father Randy represented Dorner in a series of hearings that led to his being fired from the LAPD. It is also Quan that he places at least some of the blame on in an online “manifesto” he wrote, which appears to implicate him in the Irvine shootings.

On Thursday morning two officers exchanged fire with Dorner while guarding one of the officials mentioned in the manifesto, with one officer sustaining a grazing wound. The gunman fled only to run into two other officers, whom Riverside police say Dorner ambushed — fatally shooting a 34-year-old veteran and wounding the other.

Dorner served as a patrolman with the Los Angeles Police Department from 2005 until his employment was terminated in 2008 for making false statements against a fellow officer. The California Highway Patrol released a “blue alert” on Dorner for nine Southern California counties, describing him as “armed and extremely dangerous.” An Afghanistan veteran and Navy reservist, considered a skilled marksman, authorities believe he could be a threat to police officers and their families.

LAPD chief Charlie Beck explained that Dorner may have multiple weapons at his disposal including an assault rifle. He said that his skill as a policeman makes the situation even more delicate. On Thursday afternoon police in San Bernadino County confirmed that they found his burned out truck in a wooded area in Big Bear, spurring them to launch a door-to-door search in that community. Police did not elaborate on what they found in the truck, but said Dorner was not inside.

“Of course he knows what he’s doing, we trained him,” said Beck at a Thursday press conference. “He was also a member of the armed forces. It is extremely worrisome and scary, especially to the police officers involved.”

The manifesto, which was reposted by KTLA-TV and is apparently aimed at the media, is a lengthy treatise which purports to be Dorner’s explanation for his actions. “I have exhausted all available means at obtaining my name back. I have attempted all legal court efforts within appeals at the Superior Courts and California Appellate courts,” it reads. “This is my last resort.”

In his lengthy Facebook post Dorner claims that he was railroaded by the LAPD for reporting another officer, whom he claimed kicked a suspect who was under arrest. Dorner claimed the department retaliated against him, resulting in the end of his police career and the loss of his position in the U.S. Navy Reserve. He describes white, black, Asian and Hispanic officers who he says either facilitated or ignored racism as “high value targets” and names several ranking officers within the LAPD as possible targets. The department has placed several officers under police protection.

“Citizens/non-combatants, do not render medical aid to downed officers/enemy combatants. They would not do the same for you,” Dorner writes. “Let the balance of loss of life take place. Sometimes a reset needs to occur.” He particularly threatens those involved with his termination: “I never had the opportunity to have a family of my own, I’m terminating yours. Quan, Anderson, Evans, and BOR members Look your wives/husbands and surviving children directly in the face and tell them the truth as to why your children are dead.”

But Beck said that Dorner’s case had been adjudicated and was heard by many levels of the department’s internal reviewers. He believes Dorner’s problems with the outcome are of his own making. Court records show that Dorner’s case underwent an extensive review and appeals process in which witnesses, both civilian and within the LAPD, testified that they did not see the officer kick the suspect.

“Dorner’s statements are self-serving and are the statements of someone who is extremely unhappy with his lot in life,” Beck said.

Monica Quan, 28, was the assistant women’s basketball coach at California State University at Fullerton. Her fiance, Keith Lawrence, 27, was a University of Southern California public safety officer. The two were found dead in the parking structure of their Irvine condo.

Meanwhile, police protecting one of Dorner’s possible targets appear to have accidentally shot two innocent bystanders on Thursday. The Los Angeles Times says that two women were shot while delivering newspapers in Torrance, Calif. — apparently having been mistaken for the gunman. Both women were being treated at area hospitals.

Police also report that Dorner tried to steal a boat in San Diego in an attempt to flee to Mexico. Police believe Dorner approached an 81-year-old man at the Point Loma Yacht Club on Harbor Island with a firearm and demanded his boat on Wednesday. But the boat’s motor malfunctioned, forcing him to scrap his plans. He took the boat owner’s cellphone and left him unharmed. Police say a briefcase belonging to Dorner and his badge were found not far from the scene of the attempted theft.

Can we for once and for all address the catastrophic lack of mental health care in this country? We are being distracted by this irrelevant gun debate when the problem is right there in front of us- we dont identify, diagnose, and treat the majority of mentally ill people in this country and that is why we have mass killngs period.

Having read his online manifesto, we clearly have a madman willing to murder as many people as necessary to "clear his name," and one quite willing to die to achieve this and his other objectives. I see no compelling reason why the LAPD would not be open to an independent inquiry of his accusations provided he surrenders voluntarily and without condition.

I don't think this is so much a gun control issue this time around. The whole story is tragic and the only person to really blame here is dorner. He was the one who lost control and I know personal responsibility is seldom attributed to hasty actions but that seems to be the problem here. Maybe he needed psychiatric help I don't know.

On a side note I am also confused as to how the officers mistook two women for this man. He is fairly distinct. But I was not in their position so I'm not going to jump on the anti-cop bandwagon.

@easyed -- It is the media, democrats, and other stupid people that call any semi-automatic rifle that looks scary an "assault" rifle. The NRA actually knows what they are talking about, unlike yourself.

Well when seconds count, cops are minutes away. Continue to live in your medcated world of the Kardashians and nothing will ever go wrong. Also assualt rifles are already banned in California. So bans must work right??

@CourtneyBlack@easyed It doesn't matter what it's called or if anyone calls it correctly or not. All that matters is getting multi-round killing machines (Glocks, AK15's, and more) out of the hands of idiots.

@lifepanels @lifepanels @lifepanels Yes getting guns out of the hands of idiots is key .... Not getting guns out of the hands of the vast majority of law abiding gun owning Americans... And that's what liberals and uneducated reactionists like yourself don't get. Two points I need to educate you on. Number one is the fact that banning weapons will not get them out of the hands of the criminals who kill like this dormer idiot or your average gangbanger loser. It will simply take the guns out of the hands of good Samaritans who might be in the right place at the right time to save someone in your family who's being raped or attacked at gun or knife point. You would be hard pressed to find a stranger to stand up for you or your loved ones when they are out gunned because people like you helped take their weapons away. Second point is that bans are an emotional and illogical path to solving the problem at hand that has already been proven to not only be ineffective but also make the problem worse. Do some research lifepanels. Every state in the country that has relaxed, pro gun rights laws has seen drops in crimes (Texas, Wisconsin, etc) relative to how relaxed their gun laws are. Hell, I live in Henderson Nevada which has been named one of the safest cities in the nation. We have relaxed gun control laws and getting a cow is not extremely difficult. However you go to northern Las Vegas 30 miles from here and crime is high cause that area is anti gun even though north vegas still has to follow the states gun rights laws. On the flip side you look at states with communistic gun laws ( California, New York, etc) and crime is through the roof.... I know first hand because I lived in Cali for 30 years. Make decisions and base your opinions on logic not emotion.... You ban guns and the only ones who will obey the laws are the good guys ...and that will lead to more victims
